Annunciators : Programmable Alarm Annunciator

An annunciator is an electronically-controlled board, typically using light emitting diodes (LED) to indicate the state of an electronic component. Annunciators come in many design styles and are often customized to a specific application. An programmable alarm annunciator is typically designed to specifically monitor sensors for fault conditions and safety concerns and allows the user to customize the alarm conditions, sensing thresholds, alarm sequencing, and other actions.
